Advancing Usability of an Immersive Virtual Reality Team Training Environment within a Learning-Engineering Cycle

A Virtual Reality (VR) training environment for Tactical Combat Casualty Care (TC3) was built around the Team Dynamics Measurement Framework (TDMF) to address the need for adaptive team training inside a Casualty Collection Point (CCP). Guided by a Learning Engineering (LE) process, we embedded this work within nested LE cycles that emphasized iterative refinement. Two rounds of heuristic evaluation were conducted using a combination of VR and domain specific heuristics to assess the system’s usability and its support for team training. This paper focuses on findings from the second heuristic evaluation which contribute to the design of scalable, team VR training aligned with LE principles.
